# A few helpful tips about the Rules file:
#
# * The string given to #compile and #route are matching patterns for
#   identifiers--not for paths. Therefore, you cant match on extension.
#
# * The order of rules is important: for each item, only the first matching
#   rule is applied.
#
# * Item identifiers start and end with a slash (e.g. /about/ for the file
#   content/about.html). To select all children, grandchildren,  of an
#   item, use the pattern /about/*/; /about/* will also select the parent,
#   because * matches zero or more characters.
